This article is mainly focused on the most repeatedly asked and the latest updated Array Interview Questions in C/C++  that are appearing in most of the C/C++ interviews. If you are looking for “Array Interview Questions in C/C++” or “advanced questions on array in C/C++, then you at the right place. Here I have tried […]

The atexit function registers the function pointed to by func and this registered function called without arguments when the program terminates normally. In case of more than one atexit function, the registered functions are called in the reverse order of their registration (i.e. the last function specified is the first to be executed at exit).

The abort function terminates the execution of a current process abnormally. When the abort function is called it raises the SIGABRT signal to cause abnormal termination of the current process. The abort function defined in the ‘stdlib.h’ header file, so you have to include the header file before using it. Syntax abort in C: //Syntax

The div, ldiv, and lldiv, functions compute quotient (numer / denom ) and remainder (numer % denom ) in a single operation. These functions div, ldiv, and lldiv, are defined in stdlib.h header file and returns a structure that comprises the quotient and the remainder. So let see these function one by one with some

The abs, labs, llabs functions compute the absolute value of an integer. These functions abs, labs, llabs are defined in stdlib.h header file. The behavior of these functions is undefined if the result cannot be represented by the return type. So let see these function one by one with some example code. abs(): The abs

The strcspn function scan the string pointed to by s1 and computes the length of the maximum initial segment of the string which consists entirely of characters not from the string pointed to by s2. It means strcspn scan s1 until the first occurrence of any characters that are part of s2. Syntax strcspn in
